Hard and abrasive formations Tricone Drill Bit 6 3/4" 732 171mm
LUGAND SHIRTTAIL ENHANCEMENT
1. Conventional Shirttail DesignThis shirttail features
a”terraced”design,which increases escape area and the bailing
velocity and decreases cuttings regrind and wear on shirttail and
Hardmetal and wear resistant carbide were applied to shirttail and
2. Particular Shirttail Design
This shirttail features a”terraced”design,which increases eacape
area and the bailing velocity and decreases cuttings regrind and
wear on shirttail and shirttail lop.
Hardmetal was applied to shirttail lip and lug.Wear resistant
catbide on shirttail lip and lug and around the”terrace”lower part
of shirttail lug.
1. Tailored insert shapes and grades manufactured using
state-of-the-art tungsten carbide technology for different
formations having varied drillability and compressive strength,to
provide an optimum match beteen inserts wear resistance and
2. By using computer simulation of the rock bteaking at the bottom
of the hole,Shareat’s engineers are able to design the best inserts
space to ensure the most balanced load on each insert.
3. Double rows of gage inserts For better maintaining full gage
· The bit should be kept indoor with dry and well ventilated
conditions at 10-33℃ and kept from sunshine and rain. Stored under
such conditions, quality of bit is guaranteed for 3 years.
